Repeat for subsequent bytes
Full status check can be done after each byte or after a
sequence of bytes
Write FFH after the last byte write operation to reset the
device to Ready Array Mode
Operation
SR 3 MUST be cleared if set during a byte write attempt
before further attempts are allowed by the Write State
Machine
SR 4 is only cleared by the Clear Status Register Command
in cases where multiple bytes are written before full status is
checked
If error is detected clear the Status Register before
attempting retry or other error recovery
